Structural and Electrical Properties of Sintered Barium-Zinc-Titanate Ceramics
(Warsaw : Institute of Physics, Polish Academy of Science, 2011)
The aim of this work was an investigation of structural and electrical properties of sintered barium-zinc-titanate ceramics. Mixtures of BaCO3, ZnO and TiO2 were mechanically activated in a planetary ball mill up to 80 ...
Three-Axis’ Heat Loss Anemometer Comprising Thick-Film Segmented Thermistors
(IEEE, 2019)
NTC thick-film segmented thermistors were used as anemometer sensing devices. They were screen printed of thick-film thermistor paste based on modified NiMn2O4 fine powder, organic vehicle, and glass frit. Their electrical ...
Influence of prolonged sintering time on density and electrical properties of isothermally sintered cordierite-based ceramics
(Belgrade : International Institute for the Science of Sintering, 2013)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for sample preparation before the sintering process. Cordierite, a stoichiometric mixture of three different oxides (2MgO⋅2Al2O3⋅5SiO2) ...
Sintering of the mechanically activated MgO-TiO2 system
(Hanyang University Press, 2013)
Mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for a time interval from 0 to 120 minutes. The influence of the mechanical activation on the phase composition and crystal structure have ...
Electrical properties of mechanochemically activated cordierite ceramics
(Springer, 2012)
Three-component oxide mixtures were prepared containing MgO, Al 2 O 3 and SiO 2 in a 2 : 2 : 5 ratio with addition of 10% Bi 2 O 3. The mixtures were mechanically activated in a range from 5 to 240 min in a mill with ceramic ...
Microstructural and electrical properties of cordierite-based ceramics obtained after two-step sintering technique
(Insternational Institute for the Science of Sintering, 2016)
Cordierite-based ceramic materials are attracting much interest for their various applications in industry, for manufacturing multilayer circuit boards, catalytic converters, filters, thermal insulation, kiln furniture, ...
The influence of compaction pressure on the density and electrical properties of cordierite-based ceramics
(Belgrade : International Institute for the Science of Sintering, 2015)
Due to its characteristics, cordierite, 2MgO·2Al2O3·5SiO2, is a high-temperature ceramic material of a great scientific interest. Mechanical activation of the starting mixtures containing 5.00 mass% TiO2 was performed in ...
Fractal nature structure reconstruction method in designing microstructure properties
(Elsevier, 2018)
In the process of predicting materials properties, it is necessary to predict microstructures. This is important for ceramic materials, for the purpose of miniaturization and for a higher level of integration. Although the ...
Structural, electrical and magnetic properties of nickel manganite obtained by a complex polymerization method
(Elsevier, 2014)
Structural, electrical and magnetic properties of nickel manganite ceramics obtained by sintering fine powders prepared by a complex polymerization method are given in this work. The phase composition of the synthesized ...
Electrical properties and microstructure fractal analysis of magnesium-modified aluminium-silicate ceramics
(Belgrade : International Institute for the Science of Sintering, 2011)
The addition of Mg2(NO)3 and some active additives, composed of Al salts, to the mixtures of kaolinite and bentonite can provide clay compositions which, after sintering at high temperatures, produce very porous ceramics ...
